Abstract:
Electronic devices may be provided with printed circuits to which integrated circuits and other electrical components may be mounted. A first printed circuit may have a first surface with an array of contact pads arranged in rows and columns. Each column of contact pads may have a series of contact pads separated by gaps. The contact pads in each column may be staggered with respect to the contact pads in adjacent columns such that each contact pad in a given column is horizontally adjacent to associated gaps in the adjacent columns. A component may be mounted to an opposing surface of the printed circuit such that it overlaps one of the gaps between the staggered contact pads. By mounting the component to portions of the first printed circuit that do not overlap the staggered contact pads, the risk of damaging the electrical component during solder reflow operations may be minimized.
Abstract:
The described embodiment relates generally to the field of inductive bonding. More specifically an inductive heater designed for use in assembling electronics is disclosed. A number of methods for shaping a magnetic field are disclosed for the purpose of completing an inductive bonding process without causing harm to unshielded adjacent electrical components.

Abstract:
Printed circuit boards are provided with embedded components. The embedded components may be mounted within recesses in the surface of a printed circuit board substrate. The printed circuit board substrate may have grooves and buried channels in which wires may be mounted. Recesses may be provided with solder pads to which the wires may be soldered or attached with conductive adhesive. An integrated switch may be provided in an opening within a printed circuit board substrate. The integrated switch may have a dome switch member that is mounted within the opening. A cover member for the switch may be formed from a flexible layer that covers the dome switch member. Terminals for the integrated switch may be formed from conductive structures in an interior printed circuit board layer. Interconnects may be used to electrically connect embedded components such as switches, integrated circuits, solder pads for wires, and other devices.
Abstract:
The described embodiment relates generally to the field of ultrasonic bonding. More specifically, an apparatus for bonding a number of wires directly to a metal substrate in a single operation without the use of any kind of adhesive or solder is disclosed. The apparatus is an ultrasonic bonder. The ultrasonic bonder has a horn with a cavity specifically sized for the number of wires to be bonded. The ultrasonic bonder is driven at a frequency that corresponds to a resonant frequency of the wires to be bonded.
